I have had problems syncing large files using Dropbox between computers.
Plus I would never be able to afford $99 for 50GB for a year.
I suspect you could wait a while for convenience and functionality to not matter.
huh?
In comparison, amazon is offering 100 GB for the same $100 a year, and even has cheaper paid plans (e.g. $20 per year for 20 gb).
So, dropbox is currently expensive on two fronts; Amazon gives more GB/$ and also has lower-priced plans for more modest needs.
This is a big win for some users, like kunjaan and me, because we haven't been too thrilled with Dropbox's syncing abilities (tons of "conflicted copies" everywhere). Furthermore, a large portion of our data doesn't need to be synced; it simply needs to be available. This includes data like ebooks, music collection, pictures.
